      drm/radeon: add a force flush to delay work when radeon · f461950f
      Zhenneng Li authored 
      Although radeon card fence and wait for gpu to finish processing current batch rings,
there is still a corner case that radeon lockup work queue may not be fully flushed,
and meanwhile the radeon_suspend_kms() function has called pci_set_power_state() to
put device in D3hot state.
Per PCI spec rev 4.0 on 5.3.1.4.1 D3hot State.
> Configuration and Message requests are the only TLPs accepted by a Function in
> the D3hot state. All other received Requests must be handled as Unsupported Requests,
> and all received Completions may optionally be handled as Unexpected Completions.
This issue will happen in following logs:

      drm/amd/display: Include missing header · 2035590f

      The file amdgpu_dm_plane.c missed the header amdgpu_dm_plane.h, which
resulted on the following warning:

Therefore, include the missing header on the file and turn global functions
that are not used outside of the file into static functions.

      drm/amdgpu: Move psp_xgmi_terminate call from amdgpu_xgmi_remove_device to psp_hw_fini · 9d705d77
      YiPeng Chai authored 
      V1:
The amdgpu_xgmi_remove_device function will send unload command
to psp through psp ring to terminate xgmi, but psp ring has been
destroyed in psp_hw_fini.

V2:
1. Change the commit title.
2. Restore amdgpu_xgmi_remove_device to its original calling location.
   Move psp_xgmi_terminate call from amdgpu_xgmi_remove_device to
   psp_hw_fini.
